Mercedes-Benz S 430 | DiamondLube Before and After

We apply DiamondLube to a 2004 Mercedes S 430 by adding it to the engine oil and fuel. The engine is a 4.7 Liter V8 with a 7 speed automatic transmission. Even though we only added the V6 treatment, there was still a noticeable difference. The owner said the car felt more responsive during the 15 minute drive after treatment, and the startup was much smoother. To get the full effect, another bottle should be added, because we were not aware the engine was a V8. It really does matter what size engine you have, and to buy the correct kit for your vehicle, if you want to get the full effect of DiamondLube.
